I am thinking about renting this canon 400mm f2.8 ii lens for a weekend to put it on my ML-2. I have the 210mm length brackets but wonder if the entrance pupil of such lens will be beyond the maximum distance provided by the bracket

Thank you

I guess that you plan to shoot gigapixel panorama with such lens right ? If it is you don't care about Nodal Point but just to center weight on M2L.
Have a look at manual of M2 ;) http://www.nodalninja.com/Manuals/QRG_M2.pdf

I think it likely that the entrance pupil will be postioned towards the rear of the lens. maybe even beyond the end. For some lenses you need to turn the top rail through 180 degrees so that it is pointing forwards!
